The energy from the hydraulic fluid is used to move the components. This movement is achieved by using actuators in a hydraulic system. A hydraulic system can use various types of actuators that convert hydraulic energy into mechanical motion. Linear actuators convert the energy into linear mechanical motion while rotary actuators convert the energy into rotational motion.
A hydraulic cylinder is a type of linear actuator which converts the fluid power into linear motion. This linear motion is achieved by extending and retracting a piston rod by applying pressure through the hydraulic fluid or oil.
In a hydraulic circuit, the components are represented such that it clearly shows the functioning of the component without actually showing its detailed construction. This allows for easy analysis of the hydraulic circuit. Apart from the classification according to the functioning, hydraulic cylinders can also be classified according to their construction.
Their application is dependent on the requirements of the hydraulic system and a correct cylinder for a particular system ensures the maximum work accuracy with minimum financial losses along with good maintainability.
